  • Navigation system providing route-guidance and traffic information is one of the most widely used driver-support system these days. Most of the navigation system is based on the 2D map paradigm so the information is ed and encoded from the real world. As a result it imposes a cognitive burden to the driver to interpret and translate the ed information to real world information. As a new concept of navigation system, augmented-reality navigation system (AR navigation) is suggested recently. It provides navigational guidance by imposing graphical information on real image captured by camera mounted on a vehicle in real-time. The ultimate goal of navigation system is to assist the driving task with least driving workload whether it is based on the abstracted graphic paradigm or realistic image paradigm. In this paper, we describe the comparative studies on how map navigation and AR navigation affect for driving tasks by experimental research. From the result of this research we obtained a basic knowledge about the two paradigms of navigation systems. On the basis of this knowledge, we are going to find the optimal design of navigation system supporting driving task most effectively, by analyzing characteristics of driving tasks and navigational information from the human-vehicle interface point of view.

  • Augmented reality (AR) has tremendous potential in visualizing geospatial information, especially on the actual physical scenes. However, to utilize augmented reality in mobile system, many researches have undergone with GPS or ubiquitous marker based approaches. Although there are several papers written with vision based markerless tracking, previous approaches provide fairly good results only in largely under "controlled environments." Localization and tracking of current position become more complex problem when it is used in indoor environments. Many proposed Radio Frequency (RF) based tracking and localization. However, it does cause deployment problems of large RF-based sensors and readers. In this paper, we present a noble markerless AR approach for indoor (possible outdoor, too) navigation system only using monoSLAM (Monocular Simultaneous Localization and Map building) algorithm to full-fill our grand effort to develop mobile seamless indoor/outdoor u-GIS system. The paper briefly explains the basic SLAM algorithm, then the implementation of our system.

  • 현재 위치에서 목적지까지의 거리와 교통상황을 고려하여 최적의 경로를 안내하는 도로 및 교통 정보 제공 시스템인 차량용 내비게이션 시스템은 텔레매틱스의 가장 중요한 응용 분야이며 디지털 컨버전스의 핵심으로 부각되고 있다. 내비게이션 기술은 크게 2차원 또는 3차원 그래픽 기반 기술과 위성 영상이나 비디오 또는 실시간 영상에 기반을 둔 영상 기반 내비게이션 기술로 구분할 수 있으며, 최근에는 운전자의 시야에 보이는 실제의 도로의 모습을 카메라를 통해 실시간으로 취득한 후 경로 안내 정보를 부가하여 보여줄 수 있도록 하는 증강현실 기반의 실감 내비게이션이 차세대 기술로 연구되고 있다. 본 고에서는 이러한 실감 내비게이션 기술을 중심으로 국내외 기술개발현황과 한국전자통신연구원에서의 기술 개발 사례에 대하여 자세히 살펴보고 향후의발전 방향에 대해 전망해 본다.

  • Smart phone based navigation applications are very useful in everyday life. Cost-effective and user friendly navigation can be provided to the user by many applications available in market. Using the Smart phone these navigation applications provide accurate navigation for outdoor locations. But providing an accurate navigation underground space such as subway station is still a challenge. It is hence more convenient and appropriate for mobility services if the visitors could simply view the guidance of the subway station on their mobile phone, wherever and whenever it is needed. This study develops a algorithm for indoor navigation with the help of Augmented Reality(AR) and QR marker code from the entrance to the train platform for users. This indoor navigation uses AR and QR maker codes for two purposes: to provide the user link to the subway station location and to provide the current guidance details to the user. This Smart phone algorithm that uses a smart phone optical tool to decode the QR marker to determine the location information and provide guidance to the AR without indoor Maps. This algorithm also provides a module to guide mobility vulnerable to the Barrier Free route to destination.

  • The International Maritime Organization (IMO) has recognized that systemic consideration and research associated with human elements for the safe navigation of ships were required. The usability of navigational equipments based on user demands becomes a significant issue on the e-navigation field. Although many assessment and evaluation methods of usability has introduced in various fields, there is room for improvement. To this end, the primary objective of this paper is to propose a new checklist to the usability assessment of the AR-based navigation information system.
